Study of the morphology of MB2 canals in maxillary first molars using CBCT

372 human maxillary first molar teeth with three separate roots from the Dakshina Kannada population were selected for the study. Teeth with completely formed apices with no presence of any developmental defects were included in the study. Endodontically treated teeth and those with severe alterations in root canal anatomy were excluded from the study. Cone Beam Computed Tomography (CBCT) images of 372 maxillary first molars were processed using the ProMax 3D Mid (Planmeca, Helsinki, Finland) version – 4, and projected onto a Dell LED screen (Model no: E1913Sf) to observe sections in coronal, sagittal and axial views as well as a 3D reconstruction. Results showed that out of the 372 maxillary first molars evaluated using CBCT, 196 teeth showed the presence of MB2 canals (52.6%). Vertucci’s Type II canal configuration was found in 163 (83.4%) teeth, Vertucci’s Type IV canal configuration was found in 33 (33.6%) teeth.
